DOOR-OPERATING STRUCTURE.

Application filed March 19, 1925. Serial No. 16,855.

To all whom it may concern:

Be it known that I, HUGH G. PUMPHREY, a citizen of the United States,residing at Lamesa, in the county of Dawson and State of Texas, haveinvented certain new and useful Improvements in Door-OperatingStructures, of which the following is a specification, reference beinghad to the acoonr panying drawings.

This invention relates to improvements in door operating structures andhas relation more particularly to a structure of this general characterespecially designed and adapted for use in connection with a freight cardoor, and it is an object of the invention to provide a structure ofthis kind comprising a member carried by the door and coacting with thewall of the car in a manner to effect the requisite movement of thedoor.

Another object of the invention is to provide a structure of thisgeneral character comprising a bar having substantially universalconnection with the door and coacting with the wall of the car in amanner to i1npart the desired movement to the door.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved dooroperating structure whereby certain important advantages are attainedand the device rendered simpler, less expensive and othe W ise moreconvenient and advantageous for use, as will be hereinafter more fullyset forth.

Elie novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to t cscribe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view in elevation illustrating a dooroperating structure constructed in accordance with an embodiment of myinvention and in applied position, the worl-:- ing bar being shown inits normal or in operative position;

Figure 2 is a view partly in horizontal section and partly in elevationillustrating a structure as shown in Figure 1, different positions ofthe working bar being indicated by broken lines;

Figure 3 is a View in perspective of the member carried by the door forholding the working bar;

Figure 4; is a fragmentary View in perspective of the member or platesecured to the wall of the car .and with which the working bar engages.

As disclosed in the accompanying drawing, V denotes the side wall of afreight car provided with the door opening G adapted to be closed in awell known manner by the outside sliding door D. At a desired pointabove the bottom of the door are attached the outstanding supportingmembers 1 spaced apart and aligned in a direction transversely of thedoor D, eaohof saidmembers bein herein disclosed as a staplehaving itseatremities disposed through the door D proper and having engagedtherewith the holding nuts 2. I do not wish, however, to be understoodas limiting myself to any particular means whereby the supportingmembers 1 may be maintained in desired applied position.

Disposed through and rotatably supported by the members 1 is anelongated rod 8 havng one end portion extending beyond the innervertical edge of the door D, said extended portion terminating in a heada proyided therethrough with an elongated opening 5. The contact of thehead f with the adjacent vertical edge of the door limits inwardmovement of the bar or rod 3 in one direction while the contact of theoutstanding pins 6 carried by the bar 3 with the members 1 holds the baragainst lengthwise movement in the opposite direction.

A working or pinch bar B adjacent one end thereof is cut away atopposite sides to provide reduced portion 7 which is disposed throughthe elongated opening or slot 5. said portion 7 being of a width lessthan the length of the opening or slot 5 so tnat the bar B may haverequisite swinging movement to effect an opening or closing of the doorD. Initially the head 4 maybe split to permit the proper application ofthe bar B, said head being afterwards welded or otherwise closed.However, it will be understood that the bar B may be assembled withrespect to the head l in an manner which may be preferred.

Secured to the outer face of the wall W at the inner side of the opening0 is a horizontally disposed elongated plate 8 held in desired positionby the bolts 9 or the like. This plate 8 at points spaced lengthwisethereof is provided with the depressions or pockets 10 to receive theworking end extremity ll of the bar B after the bar 3 has been retatedin a direction to bring the bar B to substantially a horizontalposition. Requisite horizontal swinging or rocking movement of the bar13 with the working extremity 11 properly engaged within the depressionsor pockets 10 will result in an effective opening or closing of the doorD without defacing or otherwise injuring the door D or the wall W as nowoften occurs by the use alone of the conventional pinch bar.

The plate 8 is of a length equal to the full opening movement of thedoor D and the outer end portion of said plate 8 is provided with anoutstanding lip or flange 12 with whichthe door D contacts to limit theex.- tent ofopening movement of the door D.

From the foregoing description it is thought to be obvious that a dooroperating structure constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principles and spirit thereofand for this reason I do not Wish to be understood as limiting myself tothe precise arrangement and formation of the several parts herein shownin carrying out my invention in practice except as hereinafter claimed.

I claim 1. In combination with a Wall provide with an opening and asliding door therefor,

Lesa res a member rotatably supported by the door and extending beyondan edge thereof, said extended portion of the member being provided witha slot therethrough, a bar having a reduced portion disposed through theslot whereby the bar is supported by the member, said slot being greaterin length than the width of the reduced portion to permit the bar havingswinging movement in a direction lengthwise of the member, and a secondmember provided with spaced pockets carried by the wall to one side ofthe opening with which an end portion of the bar is adapted to engage tofacilitate movement of the door.

2 In combination with a wall provided with an opening and a sliding doortherefor, a member rotatably supported by the door and extending beyondan edge thereof said extended portion of the member being provided witha slot therethrough, a bar having a reduced portion disposed through theslot whereby the bar issupported by the member, said slot being greaterin length than the width of the reduced portion to permit the bar havingswinging movement in a direction lengthwise of the member, and meanscarried by the wall to one side of he opening with which an. end portionof the bar is adapted to engage to facilitate movement of the door.

In testimony whereof I hereunto afli my signature.

HUGH C. PUMPHREY.
